Nothing grows forever, but I suspect it will plateau and drop off slowly. One of the reasons D&D is booming is because people have a deep-seated desire for personal interaction. We're too disconnected, the hobby brings people together. Throw in the ease with which we can connect to people across the country.
There are certain risks of course. WOTC could flood the market again, causing confusion. There could be a new version of Satanic Panic. But my bet would be that we don't have a "crash" like we've had in the past. Whether or not the movies/games/TV series are successful is almost secondary.
Of course, as long as I can find 4 other people willing to put up with me as a DM I'm not sure I care.
